There are hundreds of different types of salvias, commonly called sage, but they all tend to share beautiful, tall flower spikes and attractive, often gray-green leaves. Countless sages (including the herb used in cooking) are available to decorate ornamental gardens, and new selections appear annually. They are valued for their very long season of bloom, right up until frost. Not all not hardy in cold climates, but they are easy to grow as annuals. On square stems, clothed with often-aromatic leaves, sages carry dense or loose spires of tubular flowers in bright blues, violets, yellow, pinks, and red that mix well with other perennials in beds and borders. Provide full sun or very light shade, in well-drained average soil.
